Hello,
From a zone-file of a Microsoft Active Directory integrated DNS server
I get the date/time of the dynamic update entries in a format, which
is as far as I know the hours since january 1st 1901.
For Example: the number 3566839 is 27.11.07 7:00. To calculate this in
Excel I use this:
="01.01.1901"+( A1/24-(REST(A1;24)/24))+ZEIT(REST( A1;24);0;0) (put
3566839 in field A1 and switch the format of the result-field to the
corresponding date-time format).
You might guess what I need now: I want to calculate this somehow in
python.
Sorry, but I couldn't find anything in the module time or something
else to get this calculated.
Does anyone know how to convert this time in python to something
usable or how to convert this formula in python?
Thanks a lot and regards
Dirk

I think you want the xldate_as_tuple function in the xlrd module: http://www.lexicon.net/sjmachin/xlrd.htm
It works like a champ for me:
>>import xlrd
xlrd.xldate.x ldate_as_tuple( 38980,0)
(2006, 9, 20, 0, 0, 0)

Thanks so far, that comes close to a solution I think, BUT when I
enter 3566985 instead of 38980 I get the following error:
Traceback (most recent call last):
File "test.py", line 20, in <module>
print xlrd.xldate.xld ate_as_tuple(35 66985,0)

xlrd.xldate.XLD ateTooLarge: 3566985
Do I have to use another function of this module? My number is 2
digits shorter than yours. What is 38980 representing?

Your guess appears to be off by a couple centuries.
(3566839/24)/365 = 407
For Example: the number 3566839 is 27.11.07 7:00. To calculate this in

Dirk
Excel stores dates as floating point
numbers; the number of days (or fraction thereof) since
12/31/1899. So 38980.0 is midnight 9/20/2006. You think your numbers
represent
the number of hours since 1/1/1901?
3,566,985 hrs/24 hrs in a day = ~148,618 days
148,618 days/365 days in a year = ~407 years
Am I doing the math wrong?

If it *is* then the easiest way is this:
<code>
import datetime
print datetime.date (1901, 1, 1) + datetime.timede lta (hours=3566839)
</code>
But, as someone pointed out, that puts you somewhere in 2300.
Where are you getting the 1901 from (and the hours, for that
matter). If it's based, as AD dates are, for example, from 1601,
then the calc becomes:
<code>
import datetime
print datetime.date (1601, 1, 1) + datetime.timede lta (hours=3566839)
</code>
which looks more realistic. But frankly I'm guessing.

(3566839/24)/365 = 407 - YES I did this calculation too and was
surprised. But if you try this out in MS Excel:
="01.01.1901"+( A1/24-(REST(A1;24)/24))+ZEIT(REST( A1;24);0;0) (put
3566839 in field A1 and switch the format of the result-fieldby right-
click on it to the
date format "14.3.01 13:30")
and then replace 3566839 by, let's say, "2", Excel calculates the date
01.10.1901 2:00 AM. Try out other values like 5 or 24! So I thought
3566839 represents hours.

Additional to my last posting: if you want to try this out in Excel
you should replace the command "REST" by the english command what
should be something like "remainder" .
